Abstract: BF&N 6956 LINEAR SOLENOID DEVICE Abstract of the Disclosure A linear solenoid device includes a stator defining a cylindrical stator opening, and a pair of axially spaced cylindrical stator pole surfaces.  An armature is mounted within the stator opening for movement parallel to the stator pole surfaces.  The armature defines a pair of armature pole surfaces which overlap the stator pole surfaces by varying areas as the armature is moved.  Annular air gaps are defined between the stator pole surfaces and the armature and the armature has mounted thereon a pair of cylindrical radially polarized permanent magnets, each such magnet being adjacent one of the armature pole surfaces.  When a stator coil is energized, movement of the armature results from the varying reluctance across the air gaps as the armature pole surfaces overlap varying areas of the stator pole surfaces and, also, from repulsion of the permanent magnets.  As a consequence, higher force outputs are attainable.

Abstract: ABSTRACT The invention relates to a process and apparatus for carrying out function tests on internal combustion engines using the idle-acceleration method. In such a test, the engine is subjected to at least one acceleration cycle, in a condition of being disconnected from the load. The various moments of inertia of the engine, including clutch plates and flywheel, cause effective loading on the engine. In this way loading cycles may be simulated by varying the positive or negative acceleration value. The invention now proposes a preparation cycle before the actual test cycle. During the preparation cycle, the acceleration values which depend on the individual engine power output are measured and the actual test cycle is corrected in dependence on the result of the measurement operation, in such a way that the predetermined acceleration values and thus also the loading values are maintained.

Abstract: ABSTRACT OF THE DISCLOSURE           In an optical recording system for both reading and writing, the laser beam is projected to the media through a diffraction grating which generates a plus one and minus one order beam ahead of and behind the main zero order beam.  The grating is driven by an oscillating driver so as to wobble in a fashion which leaves the zero order beam unaffected but causes the plus one and minus one order beams to move inwardly and outwardly, radially, with respect to the information track on the media in opposite fashions.  The wobbling plus one and minus one order beams are used to generate differential signals from separate detectors and are passed through a band pass filter to generate a radial position error signal which may be used to drive the write/read head inwardly or outwardly to remain positioned over a particular information track.
